Move the definitions to drivers/pci and let the architectures select
them.  Two small differences to before: PCI_DOMAINS_GENERIC now selects
PCI_DOMAINS, cutting down the churn for modern architectures.  As the
only architectured arm did previously also offer PCI_DOMAINS as a user
visible choice in addition to selecting it from the relevant configs,
this is gone now.

I reordered this so it 'bool' comes first.

config PCI_DOMAINS
       bool
       depends on PCI


config PCI_DOMAINS_GENERIC
       bool
       depends on PCI
       select PCI_DOMAINS


Of course, it is just a matter of slight taste.
I just wanted the code to look consistent.
